No more struggling with bypass loops. The EASZ-1 is manufactured to fit your process line which ensures that maximum flow rate is available to the sensing elements. Completely fabricated out of 316 stainless steel to suit almost any application and a simple set up and calibration procedure , combined with low powered digital circuitry, the EASZ-1 is the watercut meter of choice.
Rather than forcing operators to select limited size and models , the EASZ-1 can be manufactured to any line size commonly found in the industry . It's simple component design and rugged construction make it an excellent choice for all types of upstream or downstream operators.
Not all conditions are the same for every operator. For those of you who want the best results out of your BS&W measurements, EESIFLO draws on its members 22 years of experience.

We not only offer our products but our expertise in the areas of static mixing through EESIMIX which enables us to provide complete solutions to those of you looking for “something better” than what is currently being offered. This might include our upstream static mixers, sampling ports and other accessories to ensure a representative sample and a representative calibration and measurement.

All EASZ-1 products are manufactured to the highest quality standards and acceptable delivery schedules. Our worldwide network of trained engineers are ready to assist you at any stage of your current requirements.

Water Cut Definition

"Watercut" is a term used in production testing. It is the ratio of water produced compared to the volume of total liquids produced.

A common type of water cut meter measures the water content (cut) of a specific product as it flows through a pipe. The water cut meter measures the differential characteristics of water and other components of the liquid to determine the percentage of water. This can be done by various methods including dielectric measurements (capacitance) microwave, infra red and other inferential techniques. Verification of these can be achieved by the use of automatic online crude oil sampling systems where a mixed sample can be taken to a laboratory to be tested using volumetric/coulometric devices. The Karl Fischer titration test is a common on.

Water cut meters are typically used in the mineral oil industry to measure the watercut of oil flowing from a well, produced oil from a separator, crude oil tansfer in pipelines and in loading tankers.

A desalter is a process unit on an oil refinery that removes salt from the crude oil. The salt is dissolved in the water in the crude oil, not in the crude oil itself. The desalting is usually the first process in crude oil refining. The salt content after the desalter is usually measured in PTB - pounds of salt per thousand barrels of crude oil. Another specification is Basic sediment and water or BS&W

The EESIFLO EASZ-1 low range units can be used in the desalting process monitoring of BS&W either in new desalter units or retrofitted to existing applications where accurate online determination of BS&W is necessary. The standard units are intrinsically safe
